Abstract

The invention discloses a road surface unevenness measuring device, and relates to the technical field of road measuring equipment. The device comprises an outer frame and an inner frame, the inner frame is in linear guide fit with the outer frame through a plurality of first linear ball guide sleeves; a telescopic driving device for driving the inner frame is mounted on the outer frame; a plurality of support adjusting devices are mounted on the peripheral side of the outer frame; a plurality of telescopic displacement measuring devices are mounted on the inner frame; four wheels are mounted on the outer frame; one end of the outer frame is connected with a tractor through a trailer connecting frame; and a power supply and a signal acquisition display are also mounted on the outer frame. Through the combination of the outer frame, the inner frame, the first linear ball guide sleeve, the telescopic driving device, the support adjusting device, the telescopic displacement measuring device, the wheels and the trailer connecting frame, the whole body is convenient to move and support at a fixed point, and the detection area is large; and calculating the range, variance and standard deviation of the displacement according to the displacement data list of the same group to reflect and evaluate the flatness of the road surface.

Description

technical field [0001] The invention belongs to the technical field of road measurement equipment, in particular to a road surface roughness measurement device. Background technique [0002] Roads are the infrastructure for all kinds of trackless vehicles and pedestrians; according to their use characteristics, they are divided into highways, urban roads, rural roads, factory and mine roads, forestry roads, test roads, competition roads, automobile test roads, and workshop passages. As well as school roads, among which high-demand roads are represented by airport runways. During the construction of the airport road, in order to ensure the quality of the road, it is necessary to measure the smoothness of the road. At present, the measurement of the road smoothness is generally measured by a spirit level. Whether the local road is smooth or not, causing local road bulges and depressions, affecting the quality of the road. [0003] The Chinese utility model patent with public...
